Many studies h ( http: / / www.21cnjy.com )ave been conducted to find the deeper benefits of listening to and playing music.The growing field of music treatment is presenting increasing amounts of evidence that point toward the greater powers of music.21cnjy.com
Emotional benefits
The right song c ( http: / / www.21cnjy.com )an put anybody in a better mood.Most people turn to certain songs to improve their moods.The main reason behind it is that music has the ability to express our feelings better than any other medium.In addition，we have favourite songs for particular situations because we tune into the melodies (悦耳的音调) that catch our nerves the best.
Music and exercise
Have you ever noti ( http: / / www.21cnjy.com )ced how out of breath you get when listening to an exciting song while doing exercise at the gym？It has been suggested that stimulating (刺激的) music can actually increase muscle tension，while sedative (镇定的) music decreases it.21·cn·jy·com
It has also been p ( http: / / www.21cnjy.com )roved that music can improve motor skills.An experiment conducted on a group of elementary students proved that children learning basic motor skills such as throwing，catching and jumping while listening to music did better than those with no music.
Chronic (慢性的) pain relief
Music has the abi ( http: / / www.21cnjy.com )lity to ease the sense of chronic pain.In fact，according to a paper in the Journal of Advanced Nursing，music can reduce chronic pain by 21%.The paper reports that 60 patients in an experiment were divided into two groups—music and no music.The results showed that people who listened to music for an hour each day for a week had improved physical and psychological diseases compared to those who did not.www.21-cn-jy.com

When I was at scho ( http: / / www.21cnjy.com )ol，our teacher often said，“You are what you eat.” She wanted us to eat the right food to be healthy.
Japanese people a ( http: / / www.21cnjy.com )re said to be the healthiest in the world. They eat rice and fish and vegetables every day. They drink green tea or water when they’re thirsty, and snack on dried fish, fruit or nuts. So we can believe that you become what you eat. When you know the advantages of different kinds of food, you can use your knowledge well and eat what you want to become.
Have you ever heard any of the following advice
Lettuce or m ( http: / / www.21cnjy.com )ilk can make you sleepy while peanuts or dried fish will stop that feeling.
To keep your teeth clean, you should eat apples often.
Garlic (大蒜) helps to prevent colds.
Future restau ( http: / / www.21cnjy.com )rants might be named after what they hope to create. Let’s take the restaurant “Winners” as an example. Its menu would list dishes specifically designed to help you win sports games. There would be rich tomato sauce (调味汁) full of vitamin C and soft vegetables. All this would have a little fresh cheese on the top—just enough to help you get a good night’s sleep.
What will happen ( http: / / www.21cnjy.com ) to junk food in the future If ice cream is not good for children, can’t we give them fat free, sugar free tofu ice cream We are told dried fruit is a healthier snack than biscuits, so some biscuit companies are making biscuits with more vitamins. So in the future, you might be able to eat your way to health!
5． What’s the best title for this passage

A
The food we eat seems ( http: / / www.21cnjy.com ) to have profound effects on our health.Although science has made big steps in making food more fit to eat，it has，at the same time，made much food unfit to eat.Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well.That food is related to illness is not a new discovery.In 1945，some researchers realized that things commonly used to keep color in meat and other food additives (添加剂) caused cancer.www.21-cn-jy.com
Yet，these add ( http: / / www.21cnjy.com )itives remain in our food，and it is difficult to know which things on the wrappings (包装) of food are helpful or harmful.The additives we eat are not all so direct.Farmers often give penicillin (青霉素) to their animals，and because of this，penicillin had been found in the milk of cows.Sometimes similar things are supplied to animals not for their health，but just to make a profit (利润)．21·cn·jy·com
The farmers are sim ( http: / / www.21cnjy.com )ply trying to fatten the animals in order to get higher price on the market.Although some countries have tried to control such things，the practice continues.

The key to preventi ( http: / / www.21cnjy.com )ng and recovering from subhealth，according to some medical experts，is to form good living habits，alternate work and rest，exercise regularly，and take part in open air activities.【来源：21·世纪·教育·网】
As for meals，people ( http: / / www.21cnjy.com ) are advised to eat less salt and sugar.They should eat more fresh vegetables，fruit and fish because they are rich in nutritional elements—vitamins and trace elements (微量元素)—that are important to the body.【来源：21cnj*y.co*m】
Nutrition experts ( http: / / www.21cnjy.com ) point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract.They also say that a balanced diet is very helpful in avoiding subhealth.21*cnjy*com
5． According to this passage，which of the following is right
A．When you are in a ( http: / / www.21cnjy.com )state of subhealth，you should stay home and keep silent.
B．When you are in ( http: / / www.21cnjy.com )a state of subhealth，you should go to see a doctor and buy some medicine.

If you eat local，th ( http: / / www.21cnjy.com )ere is a good chance you find more ways to eat healthy and that is what is really so important.Eating local doesn’t mean eating at your neighborhood fast food place.It means that you purchase food items that are produced locally.2-1-c-n-j-y
More and more lar ( http: / / www.21cnjy.com )ge chains are also starting to carry “locally produced” foods，especially in the summer.They have all expanded their organic product line because time is showing this is more than a trend.Sometimes it isn’t always possible to buy local fruits and vegetables，especially in the parts of the US that have “winter” where hard ground and cold temperatures make growing impossible.During those times，you can still shop locally and smartly.
When possible，purc ( http: / / www.21cnjy.com )hase organic products.This is especially true for fruits and vegetables.During summer months，in particular，it won’t take you long before you really taste the difference between fresh and local and transported goods.【出处：21教育名师】

The same rul ( http: / / www.21cnjy.com )e for production applies to eggs and dairy products.Animals raised in a natural environment and fed properly will result a higher quality，more nutritious product.

Carrots are very ( http: / / www.21cnjy.com )common throughout the world.They are easy to grow and easy to harvest.They taste good.And they contain a lot of carotene(胡萝卜素)，which the body changes into vitamin A.【版权所有：21教育】
When people think o ( http: / / www.21cnjy.com )f carrots，they usually create a mental picture of a long，thin，orange colored vegetable.But carrots come in many different sizes and shapes.And not all carrots are orange.For example，Paris Market carrots are about five centimeters around.Imperator carrots are thin and about twenty five centimeters long.And Belgian White carrots are，as their name suggests，white.
For the best resul ( http: / / www.21cnjy.com )ts，carrots should be grown in sandy soil that does not hold water for a long time.The soil also should have no rocks.Weather，soil conditions and age will affect the way carrots taste.Experts say warm days，cool nights and a medium soil temperature are the best conditions for growing carrots that taste great.
The best way to ( http: / / www.21cnjy.com ) judge if a carrot is ready to be harvested is by its color.Usually，the brighter the color，the better the taste.
Most people do ( http: / / www.21cnjy.com ) not know that carrots can be grown during the winter months.If the winter is not cold enough to freeze the ground，you can grow and harvest carrots the same way as you do during the summer months.
Carrots are prepared ( http: / / www.21cnjy.com )and eaten in many different ways.They are cut in thin pieces and added to other vegetables.They are cooked by themselves or added to stews.Or，they are washed，and eaten just as they come out of the ground.

Growing up in Philade ( http: / / www.21cnjy.com )lphia，Lieberman started cooking with his stay at home dad when he was seven.His food loving family had two kitchens，and he quickly learned what was the best way to bake his cakes.Lieberman improved his kitchen skills greatly during a year abroad before college，learning from a cook in Italy and studying local specialties in Germany，Spain and France.At Yale，he was known for throwing dinner parties，single handedly frying and baking while mixing drinks for dozens of friends.Just for fun，he and some friends decided to tape a show named Campus Cuisine about his classmates how to do things like making drinks out of dining hall fruit.That helped the show become very popular among the students.They would stop Lieberman after classes to ask for his advice on cooking.Tapes of the show were passed around，with which his name went beyond the school and finally to the Food Network.

Moving in wi ( http: / / www.21cnjy.com )th a boyfriend causes women to eat more unhealthily and put on weight.But the opposite is true for men，whose long term health benefits when they move in with a female partner.

Women still have the ( http: / / www.21cnjy.com )strongest long term influence over the couple’s diet and lifestyle，as they still have the traditional role of shopper and cook in most households.
The report，by Ne ( http: / / www.21cnjy.com )wcastle University’s Human Nutrition Research Centre，reviewed the finding of a variety of research projects from the UK，North America and Australia，which looked at the eating and lifestyle habits of couples.

Women also use food ( http: / / www.21cnjy.com )as a comfort when dealing with emotional stress and have been found to gain weight when a relationship ends，while the same finding has not been observed in men.
Many couples report ( http: / / www.21cnjy.com )ed food as being central to their partnership，and eating together in the evening was particularly important to many.21世纪教育网版权所有

Looking at the ( http: / / www.21cnjy.com )picture，I can see two cactuses growing in a large area of desert.The mother cactus is holding an umbrella to protect the baby cactus from the baking sun.But against her good wish.the baby cactus is bending down and turning weak in the shade of the umbrella.
This makes me think of what happens in our daily life.
Like the mother cactus ( http: / / www.21cnjy.com ) in the picture，parents are making every effort to create a comfortable environment for their children.But unfortunately，they have forgotten an important fact：No one can grow up without experiencing pain and difficulties.Too much protection from parents has a side effect on children.Just like the baby cactus in the picture，how can it grow up healthily without sunlight
So dear parents，please ( http: / / www.21cnjy.com ) throw the umbrella away.Let children face whatever may lie ahead of them so that they will be able to grow naturally.

As_computers_ ( http: / / www.21cnjy.com )are_being_used_more_and_more_widely_inour life，they have brought us a lot of convenience.However，attention should be paid to their bad effects on people’s health.
To begin with，the brig ( http: / / www.21cnjy.com )ht screen and the frequently rolling words on it do much harm to our eyes，which gradually weaken our eyesight.Besides，depending too much on computers may lead to a worse memory.Most importantly，when using computers，people tend to sit before them for a long time.That is why many people often feel uncomfortable on the back.And some may even get too fat.
To improve the si ( http: / / www.21cnjy.com )tuation，I think there should be a short rest every other hour to relax our eyes and brain.What’s more，people should avoid using computers unless necessary.After all，we can keep out of the trouble they bring us if we use them properly.
